Zephaniah E. Loss-Cutler-Hull 0353148240 tools/power x86_energy_perf_policy: Fix argument parsing ... The -w argument in x86_energy_perf_policy currently triggers an unconditional segfault. This is because the argument string reads: "+a:c:dD:E:e:f:m:M:rt:u:vw" and yet the argument handler expects an argument. When parse_optarg_string is called with a null argument, we then proceed to crash in strncmp, not horribly friendly. The man page describes -w as taking an argument, the long form (--hwp-window) is correctly marked as taking a required argument, and the code expects it. As such, this patch simply marks the short form (-w) as requiring an argument. Signed-off-by: Zephaniah E.
